jwuentoz Patented Oct. 18, 1932 UNITED STATES PATENT OFFICE HENRY J'. THEIS, OF DAYTON, OHIO, ASSIGNOR TO DAYTON SCALEOOMPANY, OF DAYTON, OHIO, A CORPORATION OF NEW JERSEY SLICING MACHINE Application led March 29, 1930. Serial No( 439,939.

This case is an improvement on application Serial No. 425,184, assigned to the assignee of the instant case and relates to detail improvements in a food slicer.

Particularly, it is an object of the invention to provide an article feeding device with improved means to guide it for movement relative to the knife.

More specifically, the object is to provide a novel anti-friction connection between the feeding device and the support therefor.

Other objects and advantages will be hereinafter set forth in the accompanying specification and claims, and shown in the drawings, which by way of illustration show what is now considered to be the preferred embodiment of the invention.

Fig. 1 is a view of the machine from the feeding side;

Fig. 2 is a rear view of the clamp;

Fig. 3 is a vertical section through line 3 3 of' Fig. 2;

Fig. 4 is an enlarged view of the rear of the slide assembly;

Fig. 5 is a section on line 5-5 of Fig. 6;

Fig. 6 is a section through the ball race assembly on line 6-6 of Fig. 5;

Fig. 7 is a section on line 7 7 of Fig. 2; and Y Fig. 8 is a detail of the clamp.

Referring to Fig. 1, vthe machine includes a rotary knife 10 driven by belt 11. At the side of the knife is a gage plate 12 adjustable to determine the thickness of slice to be cut by the knife. The base 13V of the machine has a pair of posts 14, one at each end for carrying a round rail 15. A rectangular rail 16 is fixed to the base below rail 15.

The article holding carriage 17 is provided with a hole through which rail passes. A vertical extension 18 of the carriage has j ournalled at its end, a roller 19 engaging the side of rectangular rail 16.

The carriage 17 is thus guided for movement past the knife by rails l5 and 16.

The carriage 17 has fixed to the rear of the side nearest the knife by means of screws 24, a flat rail running parallel to said side.

Rail 25 has V-shaped grooves 26 in the upper and lower edges, the grooves serving to guide aclamp carrier 27 for movement towards the plane of the gage plate as will be more fully described below. Y The lower end 28 of the carrier 27 has fastened to the back side thereof upper and low- 5 er bearing assemblies comprising solid bars 30 having one edge 31 formed with V-shaped grooves 32 complementary to the V-shaped grooves 26 of rail 25. The opposite edge 33 is formed with a bullet shaped groove 34. 0 The ends of the bar are slotted out leaving projecting sides terminating in arcuate edges. Holes 35 are drilled through the end side portions and located so that a semi-circular cavity is formed in the solid portion of the bar contiguous to the slotted end. The grooves 32 and 34 are thereby joined by a concave semi-circular wall; Bushings 36 when tted in the holes 35 complete a continuous track formed Vby parallel grooves 32 and 34 70 vand the sides of the bushings 36 extending into the slotted outer endsl of the bar. A jacket 37 is secured to the edges 33 and the arcuate ends of the sides of the bar 30, leaving only groove 32 exposed. The continuous Iig track constitutes a raceway for balls 39 and when a race assembly is on the machine, the

balls ride between groove 32 inthe bar 30 and groove 26 in track 25. The strip 37 ter.'- minates at each end in a V-shaped projection gg 40 extending into the V-shaped groove 26 in order to prevent balls 39 from riding'out of the cooperating grooves. The lowe-r raceway is fixed to the clamp u bracket end 28 by screws 43 each of which has 55 a round portion 44 (Fig. 3) journalled in a hole in the end 28, an eccentric portion 45 adjacent the round portion and seated in a bushing 36 of the lower race assembly and a threaded portion 46 to coact with nuts 47 to "e fix the screw to the end 28. By turning the screw, the eccentric portion 45 thereof serves to move the lower raceway closer vto or'fur- -ther from the rail. In this manner, the

proper adjustment between the lower race- Way andthe rail is obtained. i 'After adjustment, the screws may be prevented from turning bya socket set screw 48 engaging the side of the round portion 44 of screw 43. The'upper'raceway is non-adjustfino ably held to the clamp end 28 by screws 49 and socket set screws 50 engaging the sides of screws 49.

The clamp bracket 27, slide 25, and raceways when assembled form a single, replaceable unit held to the carriage solely by screws 24. The clamp bracket has at its upper end a post 51 through which is an opening in which is slidableabar 52 having a handle 53 and carrying at its lower end a'spiked clamp Y plate 54. The clamp plate is adapted to coact with a spiked plate 55 removably secured to the ledge 56 of clamp bracket 27 by knurled hand screws 5 7; The screws;57 coact with open bayonet slot-s 58 in the upper end of the spiked plate 55. The slots permit adjustment of the plate 5,5 at right angles to the In a slicing machine, a knife, a carriage for traversing the knife, an article feeder, upper and lower coacting guiding means provided on the carriage and the feeder for guiding the feeder transversely of the knife plane, and means for adjusting the upper and lower guiding means relatively towards and away from each other to provide the proper riding fit between the carriage'and the feeder.

gage plate and are open to provide means for easily removing the plate 55'from the 4support 56. f f

yMovement of the bracket towards the knife is adjustably limited by contact of the end f portion 28 with a screw 59 threaded into the carriage at the side adjacent the knife and retainedrin adjusted position by a locknut 60. Between spiked plate 55 and the surface of the carriage 17 is a porcelained tray 61 (Figs.

-1 and 7) ,to the bottom of which are fixed nuts and the gage plate and knife during move- Y ment of the carriage past the knife.

In operation, an article is placed on the vcarriage 17 and clamp plate 54 adjusted to clamp the article against clamp plate 55 and porcelained tray 61. The clamp bracket 27 'is then moved towards the gage plate by meansof handle 5 3 to bring the article into engagement therewith. The carriage is then moved past the knife during which a slice is cut by the knife.

It will be understood that the novel guiding means for clamp carrier 27 is not restricted Jto use with a clamp movable transversely to the knife but may be used to guide an element such as carriage 17 movable parallel to the plane of the knife.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification it will be understood that various omissions and substitutions and changes inthe form and details of thedevice illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. Itis the intention,

therefore, tobe limited only asind-icated by 'the scope of the following claim:
